hi gyus.
i have a mixed rig with 4* nitro+ 488 (Samsung), 1*5700 ASROCK Challenger, 2*1070 JS.
when i had the old config with 1*488, 1*5700, 2*1070 all worked perfect.
now, i added the 488 cards, and the miner can hang all the system. it can be after 2 minutes of mining, or after 2 days.
tryed on stock clocks - same problem.
MB - asus p8z77-lk
i5 3570
4*4 gb (2*hynix, 2*patriot)
ssd 60gb
risers
splitter 1 pci - 4 pci
with claymore - all worked fine, but i don't like claymore

thanks.
